What Poltechnet is and what it is used for This medicine is a radiopharmaceutical product for diagnostic use only. Poltechnet is a technetium ( 99m Tc) generator, which means it is a device used to obtain a solution for injection of sodium pertechnetate ( 99m Tc). When this radioactive solution is injected, it temporarily collects in certain areas of the body. The low quantity of radioactivity injected can be detected outside of the body by special cameras. The nuclear medicine doctor will then take an image (scan) of the concerned organ which can give him valuable information about the structure and the function of this organ. After injection the sodium pertechnetate ( 99m Tc) solution is used to obtain images of various body parts such as the: thyroid gland salivary glands appearance of stomach tissue in an abnormal location (Meckel diverticulum) tear ducts of the eyes The sodium pertechnetate ( 99m Tc) solution can also be used in combination with another product to prepare another radiopharmaceutical medicine. In this case, please refer to the corresponding package leaflet. The nuclear medicine doctor will explain to you what type of examination will be performed with this product. The use of sodium pertechnetate ( 99m Tc) solution does involve exposure to small amounts of radioactivity. Your doctor and the nuclear medicine doctor have considered that the clinical benefit that you will obtain from the procedure with the radiopharmaceutical outweighs the risk due to radiation. 2. What you need to know before the sodium pertechnetate ( 99m Tc) solution obtained with Poltechnet is used The sodium pertechnetate ( 99m Tc) solution obtained with Poltechnet must not be used : Page 1 of 6

2 if you are allergic to sodium pertechnetate 99m Tc or any of the other ingredients of this medicine (listed in section 6). Warnings and precautions Inform your nuclear medicine doctor in the following cases: if you suffer from allergies, as a few cases of allergic reactions have been observed after administration of sodium pertechnetate ( 99m Tc) solution if you suffer from kidney disease and/or liver disease if you are pregnant or believe you may be pregnant if you are breast-feeding Your nuclear medicine doctor will inform you if you need to take any special precautions after using this medicine. Talk to your nuclear medicine doctor if you have any questions. Before administration of sodium pertechnetate ( 99m Tc) solution you should: drink plenty of water before the start of the examination in order to urinate as often as possible during the first hours after the study. You should be fasting for 3 to 4 hours before Meckel's diverticulum scintigraphy to keep the small bowel peristalsis low. Children and adolescents Please talk to your nuclear medicine doctor if you are under 18 year old. Other medicines and sodium pertechnetate ( 99m Tc) solution Tell your nuclear medicine doctor if you are taking, have recently taken or might take any other medicines since they may interfere with the interpretation of images; and especially the following medicines: atropine, used for example: - to reduce stomach, bowel or gall bladder spasms - to reduce pancreas secretions - in ophthalmology - before administering an anaesthesia - to treat reduced heart beat or - as an antidote isoprenaline, a medicine to treat reduced heart beat pain killers laxatives (they should not be taken during this procedure since they irritate the gastrointestinal tract) if you had contrast-enhanced studies (e.g. with the contrast agent barium) or upper gastrointestinal examination (as these should be avoided within 48h prior to Meckel s diverticulum scintigraphy) antithyroid medicines (e.g. carbimazole or other imidazole derivatives such as propylthiouracil), salicylates, steroids, sodium nitroprusside, sodium sulfobromophtalein, perchlorate) (as they should not be taken for 1 week prior to scintigraphy) phenylbutazone to treat fever, pain and inflammation in the body (as it should not be taken for 2 weeks prior to scintigraphy) expectorants (as they should not be taken for 2 weeks prior to scintigraphy) natural or synthetic thyroid preparations (e.g. sodium thyroxine, sodium liothyronine, thyroid extract) (as they should not be taken for 2-3 weeks prior to scintigraphy) amiodarone an antiarrhythmic agent (as it should not be taken for 4 weeks prior to scintigraphy) benzodiazepines used for example for sedation, or as anti-anxiety or anti-convulsion or muscle relaxant medication or lithium used as a a mood stabiliser in manic-depressive illness (as both should not be taken for 4 weeks prior to scintigraphy) intravenous contrast agents for radiologic examinations of the body (as they should not have Page 2 of 6

3 been administered for 1-2 months prior to scintigraphy) Please ask nuclear medicine doctor before taking any medicines. Pregnancy and breast-feeding If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your nuclear medicine doctor for advice before you are given this medicine. You must inform the nuclear medicine doctor before the administration of sodium pertechnetate ( 99m Tc) solution if there is a possibility you might be pregnant, if you have missed your period or if you are breastfeeding. When in doubt, it is important to consult your nuclear medicine doctor who will supervise the procedure. If you are pregnant, your nuclear medicine doctor will only administer this medicine during pregnancy if a benefit is expected which would far outweigh the risks. If you are breast-feeding, please tell your nuclear medicine doctor, as he/she will advise you to stop doing so until the radioactivity has left your body. This takes about 12 hours. The expressed milk should be discarded. Resuming breast-feeding should be in agreement with the specialist in Nuclear Medicine who will supervise the procedure. Driving and using machines Sodium pertechnetate ( 99m Tc) solution has no influence on the ability to drive and use machines Sodium pertechnetate solution contains sodium Sodium pertechnetate solution contains 3.54 mg/ml of sodium. Depending on the volume injected, the limit of 1 mmol (23 mg) of sodium per dose administered may be exceeded. This must be taken into account if you are on a low-salt diet. 3.
